Its luminance value is relatively low, meaning it lacks sufficient contrast against lighter backgrounds, especially white. This can make text or graphical elements using this color difficult to read. To improve accessibility, consider pairing it with significantly lighter colors, such as shades of white, yellow, or light grey, to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as recommended by WCAG guidelines. Avoid using it for critical elements or information that needs to be easily discernible by all users. When using this color, always test its contrast against different background colors using accessibility tools to ensure compliance with accessibility standards.
